FILM-ROLL HOLDER.

Specification of Letters Patent.

Patented Jan. 23, 1917.

Application filed June 5, 1915. Serial No. 32,416.

To all whom it may concern:

Be it known that I, WILBUR I. SCHULTZ, SE, a citizen of the UnitedStates, residing at Clay City, in the county of Clay and State ofIndiana, have invented certain new and useful Improvements in Film-RollHolders; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to photographic cameras, and more particularly toan improved film roll holder especially designed to be usedinterchangeably with an ordinary dry plate holder. 2

Another object is the provision of a film roll holder including a casingof novel construction including essentially two hinged parts which maybe readily separated or swung apart to permit of the insertion orremoval of a film roll.

Another object is the provision of a film roll holder of simpleconstruction which shall be efficient in use and inexpensive tomanufacture.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawings, in which:

Figure 1 represents a perspective view of the improved film roll holder.Fig. 2 represents a longitudinal sectional view therethrough. Fig. 3represents a transverse sectional view through the holder on the line 33of Fig. 1. Fig. 4 represents a lon 'itudinal sectional view through theholder on the line 4-4 of Fig. 2. Fig. 5 represents a perspective viewof the rear section or part of the holder casing removed. Fig. 6represents a perspective view of the light excluding strips and holdertherefor removed, and Fig. 7 represents a detail view of the fastenerfor securing the parts or sections of the casing in closed position.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral10 indicates generally the casing of the film roll holder, whichincludes the front and rear parts or'sections 11 and 12 respectively,which are hingedly connected in any suitable manner at one end by ahinge bolt 12, whereby the sections or parts may be separated to permitof the insertion or removal of a roll of films. At the end opposite thehinge bolt 12 the casing is provided with a suitable type of fastener 12'for'securing the parts in closed position. The front part 11 of thecasing is formed with an exposure opening 13 behind which is slidablyand removably mounted an opaque slide 14 designed to exclude light fromthe interior of the holder when the latter is'removed from the camera.The

side walls 15 are formed integral with or se-.

cured to the front part 11 and are adapted to lie under the relativelynarrow flanges 16 formed at the sides of the rear part 12, therebyprovidin a light tight joint between the parts 0 the holder. of thesidewalls 15 at the ends opposite the hinge bolt 12 are increased in width,as indicated at 17, and the rear section or part 12 is correspondinglyshaped for a purpose which will hereinafter appear.

The side walls 15 are formed with longitudinally elongated slots 18 tothe edges of The portions 7 which are secured theadjacent longitudinaledges of a partition 19, one end of which is extended an 'ularly withinthe relatively wide end 17 of the casing, as indicated at 20, thusproviding spool containing chambers 21 and 22. A roller 23 is rotatablymounted in the end of the casing adjacent the hinge bolt 12 over whichis adapted to pass the film 24. A flanged holder plate 25 is secured tothe inner surface of the front part 11 at one end of the exposureopening 13 and secures a pair of springs 25, which normally retain lightexcluding strips '26 against the rear surface of the slide 14.

Spool supporting studs 28 and 29 are secured to the inner surface of theenlarged end .17 of one side wall 15 and are normally retained ininwardly extended position by suitable springs 30, and relatively shortshafts 31 and 32 are slidably mounted in. the enlarged portion 17 of theopposite side wall and are normally retained in inwardly extendedposition by the tension of the springs 33. The shafts 31 and32 areextended a distance laterally of the side wall of the casing andprovided with keys'34 and 35, respectively, whereby the shafts may beconveniently rotated to wind the film upon in the adjacent extremity ofthe film receiving spool 36, which latter is engaged between the stud 29and the shaft 32 and is adapted to be rotated by the shaft. A ratchetwheel 37 is keyed upon the shaft 32 between the key 35 and the outerface of the side wall and is adapted to cooperate witha pivoted pawl 38to prevent rotational movement of the shaft 32 in a direction to unwindthe film from the receiving spool 36.

The feed spool 38 is supported upon the shaft 28 and shaft 31 and may beactuated to rewind the film thereon, when the pawl 38 is disengaged fromthe ratchet wheel 37, by the key34.

In use, the fastening device 12 is re-' leased and the parts 11 and 12are swung apart upon the hinge bolt 12, and the spool 38 containing thefilms for exposure is engaged between the stud 28 and shaft 31 in theusual manner and the film backing sheet is threaded between the frontmember 11 and the adjacent portion of the partition 19, under the roller23, between the rear part 12 and the adjacent portion of the partition19 and the free end thereof is secured to the receiving spool 36, whichlatter is engaged between the stud 29 and turning shaft 32. The parts ofthe casing are subsequently closed and secured by the fastener 12 andthe first section of the film for exposure is drawn into position behindthe exposure opening 13 by rotating the key 35 on the shaft 32. Thisoperation rotates the receiving spool 36 and winds the film backingsheet thereon.

The front portion of the partition 19 is preferably formed with anaperture 40 having' a cover of translucent material through be made theholder which the markings designating the film sections are visible.When the exposure is to is positioned inthe back of the camera in thesame manner as a dr plate holder and the slide 14 is removed: thusexposing the film to the light rays admitted through the lens of thecamera when the shutter is opened.

What I claim is:

A film roll holder including a casing compris ngfront and rear sectlons,said rear sectlon having one end thereof bent downwardly, then forwardlyand upwardly'and provided with upturned flanges formed on itslongitudinal edges, said front casing COIIIPIlSlIlg a flat plate havingside walls, a rear wall, and a front wall, said plate havmg an exposureopening formed therein, a partition secured to sa d partition having adownturned end, spool carrying studs secured to said side walls of saidfront casing positioned on each side of said downturned end of thepartition, a guide roller secured adjacent the lower end of saidfrontsection, said rear section being hingedly connected to the rear wall ofsaid front section and extending forwardly to the front part thereof andoverlying said spool carrying studs, said flanges engaging the outerside of the side walls of the front section to form light tight joints,and a slide adapted to cover said exposure opening in the front section.

Intestimony whereof I afiix my signature in presence of two witnesses.
